Gabriel A. Zainescu, Rodica Roxana Constantinescu, Petre Voicu, DANA C. DESELNICU Study on the Levigation Ability of Nutrients for Soils Treated with Titanium-containing Biopolymers

Abstract:

The paper refers to obtaining protean biopolymers from Ti - tanned leather waste and it also to studying the levigation ability of nutrients for soils treated with titanium-containing biopolymers. Using tanned waste is of particular interest because it offers the opportunity to eliminate all wastes from tanning, while obtaining qualitatively and economically valuable products. Organic biopolymers represent a source of raw material for agriculture, because the composition of protean wastes provides enough elements to improve composition and rehabilitation of degraded soils, and plants can capitalize some elements: nitrogen, calcium, magnesium, sodium, potassium, titanium etc. The wastes used for this innovative procedure for obtaining biopolymers, are obtained from wet white tanned leather through a new technique based on Ti-Al tanning agents. The aim of protein waste hydrolysis is to obtain new products, state-of-the-art protein fertilizers and soil improvers designed to potentiate the transfer of nutrients obtained from the protein soil improver to plant and fruit, with the effect of stimulating the metabolism, speeding up the productive phase, stimulating the defense system of the plant and optimizing mechanisms responsible for the health of the fruit. Keywords: biopolymers, organic wastes, tannery, soil
